I have a neighbor who's quitclaim deed grants them a 'right of way to and from said [street]' via our driveway, which is not his property. The problem is that he uses my land as a turnaround, allows guests to park in my driveway next to his property, parks cars on the driveway past his property boundary (squeezing our access past and at times blocking it) and insists that we have a shared driveway. Recently I was almost in a collision with a guest of his who raced straight up and onto my land while I was trying to drive out. It has since turned quite toxic between us but he's keeping to the boundary for now. His history is to slowly creep across until I'm forced to say something and then he's okay for a few weeks or months and then it starts all over again.
I was advised to put up "Private Driveway - No Parking, No Turnaround - Do Not Block Driveway" signs on my property but, apart from them being ugly, he's really aggressive and I frankly don't want to set him off, but I know (based on his past behavior) he's going to begin the taking of liberties again.
I am not looking to do anything but keep him off of my property and keep him from blocking the driveway and allowing his guests to park on my property.
We are in Massachusetts.
